No electricity in the water. There are no motors or electrical components in the water and no restrictions on
swimming, boating, or fi shing while the unit is operating.

Easy to maintain. Most maintenance and inspection is performed from shore at the compressor enclosure.

Energy efficient operation. Robust-Aire circulates the most water with the least energy expended. Our
compressors are energy effi cient and Robust-Aire diffusers produce a superior amount of water flow, exceeding
other models by 10 to 40 percent.

Remote installation. Electrical access near the pond may not be feasible or you simply may want to locate the
system away from the pond setting. Air can be delivered to the system from .25 mile away.

Manufactured by Kasco Marine. Known for manufacturing high-quality, energy-efficient water management
equipment for over 40 years, Kasco Marine is a name you can trust.

Robust-Aire diffusers are the most efficient on the market
and create more water fl ow to aerate your pond. Diff users are
designed to provide a fi ne air bubble with the least amount
of pressure. The base is made of durable plastic and an open
port allows filling with gravel to settle. It has a raised design
that keeps the diff users performing at an optimal level above
the pond bottom. A durable, bolted, strain relief attachment
ensures that the weighted tubing will not become detached
during installation or maintenance.
